Arthritic Joints

The IR spectra of dry films of synovial fluid from normal and arthritic joints are presented. The spectra suggest the existence of CO2 clathrates in these fluids which are of remarkable stability in comparison to well-known CO2 clathrate hydrates. To our knowledge, this is the first demonstration of the formation of CO2 clathrates in biological media. The proportion of CO2 clathrates found in synovial fluid appears to vary with the state of health of joints and thus may be of use in the clinical diagnosis of arthritis.

Donor Solvent

Solutions of LiSCN in donor solvent – benzene mixtures have been investigated by solubility measurements and by infrared spectrometry. The state of aggregation of LiSCN has been obtained from the ir spectra in the ν(CN) region 2100–2000 cm−1. The selected solvents (tetrahydrofuran, pyridine, acetone, diethylcarbonate, butylacetate, ethylmethylketone) are more or less associating towards LiSCN. The addition of benzene causes an increase of the associating ability of the solvents. By changing the donor solvent and the amount of benzene it has been possible to obtain the ion pair LiNCS, the dimer (LiNCS)2, and higher aggregates in various proportions. The solvation number of lithium has been measured in solvent vibration regions. Each step of aggregation is accompanied by lithium desolvation. The coordination of lithium in all the species which are formed remains equal to 4, or slightly lower in some cases.

Abstract The analysis of the high resolution FT-IR spectra of the perpendicular bands v7 (E') at about 1550 cm -1 and V9 (E') at about 1170 cm -1 of the isotopomers 12C314N3H3 , 13C3 14N3H3 , and l2C3I5N3H3 is given. Both bands proved to be free from accidental resonances. The molecular constants of the state v7 = 1 and v9 = 1 of the isotopomers under consideration are listed. The weak difference band v9-vl4 (E" → E') of 12C314N3H3 was recorded and analyzed, using the molecular constants of v9 = 1 [this work] and V14 = 1 [of 1995], This analysis proves the quality of the molecular constants of the fundamental v14 which is IR-inactive.
